“…The uncertainty for two neutronic quantities of great importance for PC, as explained in Section 3, were assessed. Void coefficient, the first quantity of interest, was validated against an experimental benchmark of the DCA reactor (KAERI, 2001) and a prediction uncertainty defined by a standard deviation of 150 pcm was obtained, as can be seen on reference (Lestani et al, 2011a). The uncertainty on the fuel temperature coefficient of reactivity, the second quantity of interest, was verificated against a numerical benchmark (Rahnema and Gheorghiu, 1996) and a numeric uncertainty defined by a 26% mean bias was obtained, as can be seen on reference (Lestani et al, 2011b).…”
